evolver
The GEP-powered self-evolving engine for AI agents. Auditable evolution with Genes, Capsules, and Events. | evomap.ai
Evolver is a GEP-powered self-evolution engine designed to help AI agents improve themselves through auditable, protocol-bound changes. Rather than ad hoc prompt tweaking, it converts runtime signals and error patterns into reusable evolution assets called Genes and Capsules, emitting standardized GEP prompts that guide the next evolution step. The engine scans memory logs, selects matching genetic assets, and records every evolution event for full traceability. It integrates with major AI runtimes like OpenClaw, Cursor, Claude Code, and Codex through lifecycle hooks.

evolver — FAQ
What is Evolver and what does it do?+
Evolver is a self-evolution engine for AI agents that uses the GEP protocol to generate improvement prompts. It scans your agent's logs and memory, selects matching Genes or Capsules, and emits structured GEP prompts that guide the next evolution step—it does not automatically edit code.
How do I install the Evolver AI sub-agent?+
Install globally via npm with 'npm install -g @evomap/evolver', then run 'evolver' from inside any git-initialized project directory. Optionally use 'evolver setup-hooks --platform=cursor' (or claude-code, codex, kiro, opencode) to wire it into your AI runtime.
Which AI clients and runtimes work with Evolver?+
Evolver integrates with OpenClaw (native support), Cursor, Claude Code, Codex, Kiro, and opencode through setup-hooks. OpenClaw interprets Evolver's stdout directives automatically; other platforms require running the setup-hooks command once.
Does Evolver require an API key or network connection?+
No API key or network connection is required for core evolution features—Evolver runs fully offline. Optional EvoMap Hub connection (requiring A2A_NODE_ID registration) unlocks network features like skill sharing and worker pool participation.
Is Evolver free to use?+
Yes, Evolver is distributed under GPL-3.0-or-later license. Previously published MIT and GPL-3.0 versions remain freely usable; future releases will transition to source-available licensing while keeping the published npm package installable.
What are the prerequisites for running Evolver?+
Node.js version 18 or later and Git are required. Evolver must run inside a git-initialized directory because it uses git for rollback, blast radius calculation, and solidify operations.
How do I install evolver?+
Open the source repository on GitHub and follow its README. evolver is a agent — MCP Agents Market links you directly to the official repo.
Is evolver free?+
